Principal Agentic Engineer – Back-end

Role Overview

• Lead the design and development of scalable, secure, and high-performance backend systems using Python and modern cloud-native patterns.
• Apply spec-driven development practices to ensure clarity, quality, and predictable delivery.
• Organizing, distributing and translating backlog requirements from Product, UX and other disciplines, into detailed spec driven requirements for Agents to implement.
• Coordinate teams of coding agents to deliver engineering requirements.
• Design and implement RESTful APIs to support frontend, mobile, and third-party integrations.
• Architect and deliver AI-powered backend solutions, including: Vector stores and Retrieval-Augmented Generation (RAG) pipelines, integration with LLMs (e.g., Gemini, Claude, GPT-4/5), and use of AI coding agents and developer copilots to improve delivery velocity.
• Develop and maintain systems using Google Cloud Platform (GCP), with hands-on experience in, Vertex AI, Google Gen AI APIs.
• Leverage Agent Development Kits (ADKs) (e.g., Google ADK) to design and implement intelligent agent-based systems.
• Ensure systems are observable, reliable, and debuggable in production environments.
• Collaborate with engineers to design well-architected, maintainable solutions aligned with business goals.
• Mentor and guide engineers, fostering technical excellence and continuous learning.
• Partner with Project Managers and cross-functional teams to manage delivery risks and timelines.
• Communicate complex technical concepts clearly to both technical and non-technical stakeholders, including clients.

Requirements

• Strong experience with Python 3 for backend development.
• Experience designing and consuming RESTful APIs.
• Proven experience with spec-driven development.
• Hands-on experience using AI coding agents (e.g., Copilot, Claude Code).
• Strong prompt engineering skills.
• Experience working with LLMs (e.g., Gemini 3, Claude Opus, GPT-4.x/5.x).
• Experience implementing vector stores and RAG architectures.
• Experience with Agent Development Kits (e.g., Google ADK).
• Strong experience with Google Cloud Platform (GCP).
• Hands-on experience with Vertex AI and Google Gen AI APIs.
• Experience with relational and non-relational databases.
• Experience with Git and CI/CD pipelines.
• Strong system design fundamentals, including queues, caching strategies, database schema design, and API design. You know how to build systems that survive and scale in production.
• Experience designing AI agents, agent task planning, and reasoning patterns.
• Agent observability and debugging experience.
• Ability to clearly articulate goals, constraints, and context for agentic systems; reason through edge cases and failure modes; and iteratively refine agent behavior based on observed outcomes.
• Comfort understanding and integrating across the full stack; experience with TypeScript and modern JavaScript is highly beneficial.
• Excellent English communication skills (written and verbal), with the ability to explain complex technical concepts to both technical and non-technical audiences.
• Excellent command of the English language to guide coding agents to complete required coding tasks.
• Experience working effectively with fully remote, distributed teams.
• Experience working in a consultancy, agency, or professional services firm.
• Ability to thrive in a flexible, fast-paced delivery environment.
